An engraving depicting three cherubs (putti) flying amidst clouds above a landscape featuring a large domed building, likely St. Peter's Basilica in Rome. The putti carry the regalia of the Papacy: the crossed keys, the papal tiara, and a large book. Two banners ribboning through the scene are inscribed with the words "ROMAN BREVIARY".
